We have a 3TB external USB drive that I am trying to attach to some CentOS5 servers. I have tried an older Dell PE1950 and a newer R310 but neither one seems to be able to read the drive. It works no problem on windows servers/workstations and I was able to format with NTFS.
I know there are different methods for formatting large disks but this one doesn't even seem to show up as a /dev/ device. I supplied the dmesg output I see when I plug in the device. Is this a limitation of CentOS5? Do I need some additional package / driver / update?
